App Server On Linux and Database and MSSQL Server Windows Platform

We would like to install PT8.55 Application and Web Servers on Linux Servers. However, during the installation of PeopleTools on Linux Server, when we enter the MS SQL Server license, we only get the option for "Web Servers".

Application and Batch servers are missing from the list.

Oracle Support says we MUST have application and batch servers also on Windows if our database is MSSQL Server.
